IMPROVEMENT IN NAIL-SEPARATING DEVICES.

Specification forming part of Letters Patent No. 145,720, dated Dccember23, 1873; application filed December 9, 1873.

To all whom it may concern.

Be it known that I, HARVEY B. OHEss, of Pittsburg, Pennsylvania, haveinvented a new and Improved Device for Sifting Nails and Tacks, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings making a part of this specification, inwhich- Figure 1 is a perspective view, and Fig. 2 is a view of thebottom or under side. Figs. 3 and 4 are modifications of the form of. mydevice.

My invention relates to that class of devices used by nail and tackmanufacturers for the purpose of sitting the nails or tacks, in order toremove from their goods all imperfect ones,

as well as all dust and scale, which consumers have sometimes to pay forat the price of proper product per pound and it consists of thecombination and arrangement of the parts hereinafter described.

In the drawings, A represents an inclined fiat spout or trough, downwhich the nails or tacks pass from the machine to their receptacle. Thesides of this trough a a may be constructed at a right angle to theplane of the trough, or they may be made with any desired curve orincline.

It is known that in the manufacture of nails and tacks much refusematter in the way of imperfect goods necessarily follows the process ofmaking, and frequently slivers and parallel cuts are made.

The purpose of my device is to remove this and other refuse matter, and,hence, at the lower end of the spout A I cut out a piece, so as to leavean angular slot or opening, B, and secure therein a dam or breast, I),having a corresponding angle. This dam is made adjustable by means ofthe screw 0, as shown in Fig. 2, its outer ends or wings being securedby sliding hooks c c sliding on the rods cl (1 projecting from the sidesa a. These wings-may be made curved or plane faced, as

desired. Projections e c, Fig. 2, hold the adjustingscrew O in position,and c has a female screw, into which fits the screw 0, and thus affordsthe means of adjustment. By turning this screw, the distance between theend of the spout and the dam b is increased or lessened at pleasure. Thelegs 9 g sustain the spout; but any other convenient means may beadopted to accomplish the same purpose.

The operation of my device is as follows: The spout is placed under themachine and the nails or tacks are caught on its incline flat surfaceand carried down until they reach the dam I), when all the refuse passes0% through narrow openings on either side, while the perfect goods withproper heads, being too large to pass through the opening, continuealong the base of the dam to the openings h h, and are there allowed tofall into the receptacle prepared for receiving them.

I am aware the screens have been made with parallel longitudinal groovesto receive the nails, the grooves made adjustable laterally by means ofscrews but grooves retard greatly the passage of the nails from themachine to the receptacle and scatter the refuse. I avoid this objectionby means of my flat chute and arresting the refuse and dirt at the damb.

Having thus explained my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A device for sitting nails and tacks, consisting of the flat-bottomspout -A, with its sides a a, in combination with the angular dam orbreast b, adjusting-screw (J, sliding hooks c 0, and rods (1 d, allconstructed and arranged substantially as and for the purpose set forth.
